摘　　要：为提高冀南地区岗坡旱地农作物产量,应用抗旱保水剂在甘薯上进行了试验。结果表明,施用抗旱保水剂可提高甘薯幼苗成活率,促进甘薯生长,增产增收,以45kg/hm2用量效果最好。Drought-resistant and water-absorbent polymer was applied in sweet potato in order to improve the crop yields of mound land and dry land in southern Hebei Province. Experiment result showed that applying drought-resistant and water-absorbent polymer could increase the survival rate of sweet potato seedlings, the growth of the sweet potatoes, the yields and income. And the optimum dosage of drought-resistant and water-absorbent polymer was 45 kg/hm^2.
